Is yellow, it could be a very acid atmosphere, and with that density any kind of liveform would be copressed many and many times more than in our planet, as it was underwater, and I think life could exist in a planet like this, if the life can exist underwater why not here? xD (for life i mean, bacteria)

The universe is not required to be in perfect harmony with human ambition.

There are known species of Piezophiles (pressure-loving extremophiles) that not only thrive in, but require pressures over a thousand atmospheres to survive.1 So it is not totally inconceivable for at least microbial life to exist on that planet.

A good example would be the Mariana Trench and it's pancake fishes. What amazes me the most, though, is that in this planet the water is bellow the atmosphere... it's almost worrying to think how painfull evolution is under such circunstances

I wouldn't be too surprised if life can evolve there to be honest. The highest pressure environment that we know of (and can get to) on earth is the bottom of the Pacific ocean under more than 1000 atm of pressure. And we find life in that extreme environment; life which seems to be extremely old and possibly originated there.

I did wonder if water would still stable in the liquid state at 288K and 6500atm, so I checked the phase diagram and sure enough it is, but just barely.

This is just crazy 6688.2 Atmo. Pressure Also has very high gravity. 3.6231 How can life exist under these conditions I mean animal life not just bacteria. This system has 3 planets with life the other two are moons.

This is certainly not a record breaker for this category, but a worthy mention. Specially because, well, it's the definition of RARE. The system is: RS 8403-114-9-67729840-627 B6.1

2 terras with life under high atmosphere pressure, the moon is not tidally locked and has rings. The atmospheric pressure of the moon is of 1211.6 and it's roughly 100Km smaller in diameter than it's parent body.

Nvm I found an even more extreme planet this is just extreme. It has extreme mass eXtreme gravity and it even has a moon with a larger diameter than itself. 8288.2 Atmo. Pressure Gravity: 3.6888 Place: RS 1190-98-8-14355784-25 5
